SPECIFICATION forming part of Letters Patent N 0. 417,648, dated December 1'7, 1889.

Application filed August 16, 1889. Serial No. 320 917. (No model.)

To all whom it may concern: I

Be it known that we, EDMOND BURKE KNAPP and JOHN HENRY (JREsMEE, citizens of the United States, residing at San J acinto, in the county of San Diego and State of California, have invented a new and. useful Buckle, of which the following is a specification.

The invention relates to improvements in buckles.

The object of the present invention is to improve and simplify the construction of buckles and render them more durable, reliable, and easily operated.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of the improved buckle, showing it ap- Fig. 2 is a similar view of the buckle itself. Fig. 3 is a detail view of. the cam-lever. Fig. 4 is a perspective view showing the buckle applied to an ordinary strap.

Referring to the accompanying drawings by letter, A designates a buckle having horizontal side bars a, which are designed to have connected to them a back-strap B and a girth O. The side bars a are connected at their rear ends by a transverse bar a, to which is secured the'forward end of a trace D.

At the back of the buckle A, over the transverse bar a, is a loop a which serves to retain the free endof a strap E, and at its front end thebuckle is provided with two loops a which are arranged parallel and have their sides forming grooves of or recesses, in the bottom of which is journaled a cam-lever F, that bears against the under side of the strap E and forces the latter against the bars which form the tops of the loop (1, These bars are arranged a short distance apart to enable the strap to be bulged up between them, whereby the strap will be securely held and enabled to withstand all the strains incident to its use without slip- P The cam-lever F consists of a thin flat handle f and a round bar f, secured thereto and provided with journals arranged eccentrically near its lower edge, whereby when the free end of the lever is forced upward under the buckle the upper portion of the bar which lies above the journals is pressed against the strap.

The strap E is designed to be connected to a hame; but the buckle A may be attached to an ordinary strap, as illustrated in Fig. 4, and in this case the strap is attached to the transverse bar and its free end is secured similarly to the strap E.

By varying the size of the cam-lever, straps of different thickness maybe used in the same buckle, which permits the levers to be readily changed, and to prevent the strap slipping from the surface of the lever engaging the strap it may be milled, corrugated, or similarly roughened.

From the foregoing description and the accompanying drawings the construction, oper ation, and advantages of the invention will readily be understood.

What we claim is 1. A buckle provided at its forward end with the two loops arranged parallel and having their sides forming grooves, and a camlever journaled in said grooves, substantially as described.

2. A buckle comprising the side bars, the transverse bar arranged at the rear end of the side bars, the parallel loops forming grooves, and the cam-lever, substantially as described.

3. A buckle comprising the side bars, the

transverse bar connecting the rear ends thereof, the loop arranged above the transverse bar, the parallel loops, and the cain lever journaled between the parallel loops, substantially as described. 4. A buckle comprising the side bars, the transverse bar connecting the rear ends there'- of, the loop arranged above the transverse bar, the parallel loops forming grooves, and the canrlever having the bar and the eccentrically-arranged journals, substantially as described. V

5. A buckle having the parallel loops a a forming the groove between them, one end of the groove being e1osed,oombined with the cam-lever journaled in the groove and removably fitted in place, the journals of the cam resting" on the closed bottom of the groove, as set forth.

In testimony that We claim. the foregoing as our own We have hereto afiixed our signatures in presence of two witnesses.
